Adaptive MIMO in the Era of 6 GHz Wi-Fi

While there is little doubt that the introduction of 6 GHz is a great development, the mechanics of its adoption into everyday devices that we all have and love are a bit more complex. We can look at the adoption of Wi-Fi 5 (802.11ac) technology as a good model of what will most likely happen.
